CARTON.

Application sied May 18,

This invention relates to improvements in cartons, designed especially for packing brick ice-cream, butter and otlier products, and has for its object to provide a single blank from which both tlie bo-dy and cover of the carton may be formed by a few' simple folding o erations. A further object is to provide a lank consisting of a sheet of foldable material, wherein one end coniprises 'the several portions from which the bod-yV of the carton may be formedwliile the opposite end of the blank comprises the severalv parts of the cover, and wherein tlie medial portion of the blank comprises the corresponding ends of the body and cover, and serves to properly space andfintegfrally join said parts. A.l further object is l.to provide suitable locking iaps or lugs',l for facilitating the assembling of the body and cover. A further object is to provide'means for effecting the knock-down assembly of the blank for shipment and storage.` And aY further object is to generally impi'ove, simplify and lessenthe time, labor and' cost of constructing andy assembling cartons of this class. p l y I attain` these objects. by the means set forth in the detailed description whichv follows andl as illustrated by the accompany ingv drawings, in which- Figure,l l is a plan view of the blank from which, the combined-.body and. cover of the carton may be formed. Fig." 2,Y isf af topplanv view; showing, the body and cover partia-elly assembled.r Fig is a-front endelevation of theV completelyassembled carton. Fig. t ist a side elevation of the device shown in Fig.l 2. Fig. 5 is asimilar View; showing the ends of the body. andV cover folded.y and. locked. Figiv 6 is aside elevation ofthe carton shownin Fig. 3. Fig..7 is an enlarged fragmentary section; showing the meansV for locking one: ofthe. cover ends. Fig. Sis a similar View; showing the means forllocking-thefront endof the body. Fig. 9 is a view showing the knock-down carton with the body and cover extended. And Fig. l0 is a view showing the carton ready for shipment and storage.

In the drawings, 2 represents the one part' blank from which the complete cartonl is formed'. 3 is the bottom, 4 is the outer front end portion, and 5-5 are thel 1923. Serial'No. 639,846.,

.fol'dable by means of similar creases or scorings, indicated by the dotted lines 4 and 5a-5. The side portions 5-#5 are integrally joined to corresponding end flaps 6- 6 and T-f, the said flaps being foldable inwardly respectively for overlapping each vother (see Fig. 2.) ,1 by means of common transverse creases fi andl 7a. The endiiaps 6-16 a-re provided with similar slots 6%, which registerV with eachother when the said flaps are folded (see F igs; 4,1* 5S and 8), and the endportion 4 of the body is providedv with an extension 4, Whose free end inargin is formed Withaton'gue 4b, which may be woven through the slots4r 6a, for locking" the partset,y @fand 6*-6 together wheii'the said extension is folded inwardly uponthe endet. The extension@ is folded first along a crease 4L", for positioning the tongue 4b over tliesl'ots vafterf which the extension'is again folded along a? crease 4i for effecting the locking, as described. ,To make 'the locking of the end 4L more effective, tlieextension 4" is providedwithY guard lugs 4e, which are disposed at they opposite sides of the tongue 4th and bear" against the flap 6 when the folding operation is' completed,` as show-ri Fig.v 8.- The flaps 7-71^ when folded onf the creasek foverla'p` eachz other,

as shown in Figf2, and whenso positionedV said flaps. are iiit'erlf'x'zked in a Well-known manner byfmeans ofsimilar oppositely facing lugsiag'b--JZc (see Figs. l andi 2)'. The flaps;- 7-7' 'cooperate with`- the flaps' 6-'6 for holding the sides 5 5" parallelfto each othe-rfand perpendicular to the bottom 3. Each of thesidesy 5L5f is provided Withan oblique crea-sei; 59,' ,fo'rf facilitating the kn'ocldownA7 arrangement o'fthepartially assem- Elie vright-end -poivt-Vionof.v the blank 2, coin-Y prisesthei several! parts of the coverv B, which consist of the; top 8,.andth'efouter.Y end' por'- tion 9,-fthe latterffbei'ng foldable'toward's the top-by meansof a= transverse crease8l The end 9 is provided with a similar extension 9', whose free end margin is formed with a tongue 9a, which is disposed 'between guard-lugs 9b. 10-10 represent the sides of the cover B, which are foldable towards Veach other,"by means of longitudinal creases 10a. To the outer ends of the sides l0 are joined end iiaps 10b-10C, which are also foldable on the crease 8, the said flaps beingsevered from the end portion 9, as indicated by the solid lines 10d. rThe flaps 10"-10C are provided with. similar slots 10e. which are arranged to register when the fiaps are over-lapped, as shown in Figs. 3, and 7, and the end9 and the flaps 10b-1()c are suitably locked by passing the tongue 9a through the said slots, as best seen in Figs. 5 and 7. For this purpose, the extension 9 is foldable first along a crease 9, for positioning the tongue 9a over the slots 10e, after which the end 9 is finally folded along a parallel crease 9d, for passing the tongue through the said slots. The sides 10-10 are provided with oblique creases lOf, for

` facilitating the knock-down arrangement of the cap B, as shown in Figs. 9 and 10. The free ends of the sides 10-10 are preferably cut angular, as shown', for obviating interference with adjacent parts, as well as for improving the appearance of the carton,

. as shown in Fig. 6.

The .body A and cap B are integrally joined by a medial portion 12 of the blank,

i which is disposed between parallel transverse scorings 7 a-12, by means of which the portion 12 may be `folded upwardly (at the 'crease 7a).for forming the inner end Vof the body, as well as the corresponding end of the cover, which over-laps and incloses the end flaps 7 7. After the medial portion 12 is folded, 'as described, the cover B may be folded towards the body A, by means of n the scoring 12, for closing the open top of the body, as shown in Figs. 3 and 6.-

In order to economize in storage space, as well as to'facilitate the final assembling of the carton, by the vendors of ice-cream, and the like, skilled operators at the factory generally perform the greater part of the folding operations, as shown in Figs. 9 and 10. To accomplish this work, the operator first folds the blank 2 substantially as shown in Figs. 2, 4t and 5, except that the inner flaps -77 are left unfolded, as shown in Figs. 1, 9 and 10.` After the end portions .4 and 9 are folded and'locked to thel end flaps 6-.6 and 10bl0c (see Figs. 5, 7 rand 8) the operator folds'thebodyfand cap respectively along the. Vbroken lines or creases 5c and 10f, for forming the extended knockdown device, shown in Fig. A9. This latter operation may then be vfollowed by folding the cover B towards the body A, byv means of the crease 8, forforming the more com- Apact knock-down7 device, shown in Fig. 10.

The provision of the one-part blank 2, eliminates the cost and use of one die, as well as the time and labor required to operate said die, and owing to the novel design of the said blank, I am able to effect a considerable saving of material, as well as greatly reducing the labor and cost of manufacturing` and assembling the blanks ready for shipment and use. y

Having thus described my invention, what I claim, is-
